2,1-,k In a plungerv pump comprising` areeiprocating plunger, a. topvalve on said plunger, a standing valve, and-means operable by saidplunger whereby the top and 'standing valves are controlled, said VmeansComprising a rod extending int-@said plunger, said rod being'adapted tobe engaged by the plungeroii its down stroke 'to positively actuate saidtop and standing valves, a collar on said rod, a spring between saidcollar andl the standing val-ve, and aseeond spring above said collaradapted to be'engaged by the plunger.

5. In a plunger pump comprising a reciprocating .pliingei, a topl valveon the plunger, a stan-ding val-ve consisting of a cage and a ballvcheek therein, a rod slidably mounted-in saidcage andv extending intosaid plunger, a collar on said rod and a spring positioned above saidCollar adapted to be engagedby the plunger to urge the rod against theball cheek. v'
